Well it might not be right to compare FTP transfer for the problem of Browsing

rudraa,can you clarify on this.

Do you have problem in visiting/browsing new sites or with the download speed.

The former can be caused due to problem with DNS server , while once the DNS Server is queried then the downlaod speed will not matter for DNS server

regards

Sure it can be a kernel misconfiguration problem, but NOT a kernel problem if its a recent one.
Things to also check:
->PPP : PPP echoes, PMTU discovery, bad MTU
->TCP : Bad rwin (default is OK and browser little page doesn't care), Window scaling (default is OK), Select ACKnowledgment (default is OK)
->Check the differences of this webpage in windows/linux : http://www.dslreports.com/stest/0
->Incorrect routing table (route -n)
->IRQ conflict (cat /proc/interrupts), wrong driver for your Ethernet card
->Bad network (this should be the case if windows is ok, but who knows. try ping -n <ipofgateway>, try ping -n <ipofgoogle>, try ping -n <ip of dns>)
->What constantly the logs (tail -f /var/log/message)
->Try to use wget on Linux and try also on windows, print the complete header + timing ( is the page cached only if using IE?)
->Launch tcpdump or ethereal. you will need some knowledge but this step can replace all others
I've always found linux network faster or same as windows.

ya i've problem in visting/browsing the new sites and once the site is open the browsing within the site is good enough.
But as i stated earlier that in windows (#ipconfig/all) i found the same DNS server settings as i'm using on linux.
or should i ask my ISP about the DNS server ?

regards

Well I can be sure that your ISP won't know much about that too.

Do you specify the DNS manually or automatically

what do you in your resolv.conf and what do you get when u do

dig yahoo.com

dig google.com

Thanks Mr. masand.
your "dig" command gave me the idea.
after running dig twice, once for yahoo and second time for google, i found that only 202.56.230.6 was in use and not the 202.56.215.6.
and the entry of 202.56.215.6 was first in /etc/resolv.conf. I commented the 202.56.215.6 for a while........and now everything is fine.
so this DNS was the culprit.

Thanks to all the concerned guys too.

regards

But are u still sure that the primary DNS and secondary DNS were same in windows OS as well

or you just did not notice about the 1st and the second choice
